If multiple hyphenated terms share the same latter half, and I wish to list them without repeating that latter half, how should the hyphens be placed?
I will be investigating control issues in ground-based, water-based, and air-based robots.
If I do not want to repeat based, could I write:
I will be investigating control issues in ground-, water-, and air-based robots.
Is it correct to just leave a hyphen dangling after ground and water?
If not, how should it be written? I know the original sentence doesn't sound too bad, but I really just want to know the punctuation rule (or the convention in American English if there is no rule).
